What are some examples of OOP in Java?

Object-oriented programming in Java includes concepts like classes, objects, inheritance, polymorphism, and encapsulation. For example, you can create a class called 'Car' with properties like 'color' and 'model', and methods like 'drive()' and 'stop()'.

Can you explain inheritance with an example?

Sure! Inheritance allows a new class to inherit properties and methods from an existing class. For instance, if you have a class 'Vehicle', you can create a subclass 'Car' that inherits from 'Vehicle'. The 'Car' class can have additional features like 'numberOfDoors'.

What is polymorphism in Java?

Polymorphism allows methods to do different things based on the object that it is acting upon. For example, if you have a method 'makeSound()' in a class 'Animal', subclasses like 'Dog' and 'Cat' can implement this method differently.

How does encapsulation work?

Encapsulation is the bundling of data and methods that operate on that data within one unit, like a class. It restricts direct access to some of the object's components, which is a means of preventing unintended interference and misuse.
